Hi,
I've done a number of MVS 1 slot repairs recently and wanted to share it with people.
Backup RAM & Palette RAM Error

Backup RAM & VRAM

Z80 Error (MV1A / MV1AX)

BIOS Removal Fix (MV1AX)

Z80 Error - Neo-Buf Fix (MV1A)

Z80 Error - SM1 Bypass (for when you cannot find a replacement SMD SM1) & Neo-Buf Bypass (relevant when you get stuck at cross hatch on a 1A or 1AX)
The Neo-Buf bypass could be relevant to people that find the 161 in 1 menu doesn't work properly on their board as in my case. I also found that when GA11 has a fault in one direction, the Neo SD menu doesn't work either.
